Steven Spielberg insists he is still helming futuristic sci-fi film 'Robopocalypse' and is focusing on re-writing the script and cutting down the budget

Following the news that the director's futuristic action thriller was being "postponed indefinitely", Spielberg has explained production will definitely go ahead after he has completely re-worked the concept on a much smaller budget.

He told EW: "We found that the film was costing a lot of money and I found a better way to tell the story more economically but also much more personally. I found the personal way into 'Robopocalypse', and so I just told everybody to go find other jobs, I'm starting on a new script and we'll have this movie back on its feet soon."

The director's new project, based on Daniel H. Wilson's 2011 novel about a group of humans who try and survive a machine uprising, looked likely to be shelved after the recent announcement since it had already been pushed back once before in favour of the multiple Academy Award-nominated 'Lincoln'.

However, Spielberg insists he is currently focusing on the Dreamworks production's new script and will be cutting down its budget, which was originally thought to be more than $100 million.

He revealed: "Not at all. I'm working on it as we speak."

The first big-bucks storyline was penned by 'Cloverfield' writer Drew Goddard, and 'Les Miserables' star Anne Hathaway and 'Thor''s Chris Hemsworth are planning to take on the lead roles.

The film was slated for an April 2014 release, but Spielberg has now estimated a delay of six to eight months.
